ConfigurationOrientationA 3D representative volume element (RVE) model was developed to analyze the effective thermal expansion coefficient (CTE) of carbon nanotube reinforced aluminum (CNT/Al) composites. The influences of geometric configuration, orientation and volume fraction of CNTs on CTE of the ...

However, due to the relatively small temperature coefficient of MWCNT network (−0.137% K−1)38 and thermal expansion coefficient of fiberglass composites (~20 ppm/°C)30, these two effects are negligible as compared to the cross-linking effect. To better understand the correlation between ...
Due to the high optical absorption of MWCNTs and the high thermal expansion coefficient of PDMS, this combination is ideally suited for use as a photoacoustic generator. This study presents a novel method to produce photoacoustic generators based on long‐term stable MWCNT and PDMS inks with a ...

[4–6]. Compared with regular polymer, CNTs have lower expansion coefficient, which reduces the residual stress in laminated polymer composites. In addition, CNTs have favorable strength and stiffness and are capable of changing material properties such as electrical and thermal conductivity. However,...
Carbon/carbon composites (C/C composites) possess superior characteristics of low density, high strength, extremely low coefficient of thermal expansion, and high fatigue resistance. In carbonization...
When the electromagnetic waves are incident from the low conductive surface (MCP-0), the GCMCP-(0–25–100) aerogel frames have low average reflection coefficient (R, 0.27) and high average absorption coefficient (A, 0.73), which indicates that electromagnetic waves are dissipated by absorption ...
Metals such as INVAR® can be used with these coatings as INVAR has a similar CTE (coefficient of thermal expansion) ensuring proper adhesion of the coating at higher temperatures, preventing the soot from significantly building up in critical zones. Combined Catalyst Reduction and CNT Synthesis....
